Though other fertility treatments eliminate a majority of the infertility issues, certain things are not in control, and blastocyst culture is invented to eliminate those.  Studies have shown that some couples get negative pregnancy reports even after IVF with ICSI and IMSI. After the embryos are transferred into the uterus, most are damaged.

Doctors felt that there was no need to spend money and time to get negative results. Therefore, blastocyst culture became a suitable option. In this process, embryos (fertilized eggs) are grown in the laboratory until they become a blastocyst. It is a stage of the embryo 5/6 days after fertilization. It is seen that fewer embryos can survive until they develop into blastocysts.  Therefore, the remaining healthy embryos are transferred into the uterus. It is done to get the maximum success rate after a previously failed IVF process.
